To connect to MariaDB, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.

Connect to a DSN

To connect using a DSN:

$cnx = odbc_connect("CData MariaDB Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for MariaDB};User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;", "", "");
